Mechanism of improving ductility of high strength concrete T-section beam confined by CFRP sheet subjected to flexural loadingWANG Su-yan(王苏岩)1, WANG Ze-yuan(王泽源) 2(1. Faculty of Infrastructure... Office, Dalian 116600, China)Abstract:For the purpose of inventing a new seismic retrofitting method for the reinforced high strength concrete (HSC) T-section beam using carbon fiber reinforced polymer......
powder in the precursor on the open porosity and bending strength of stainless steel foams (SSFs) with 3-D open cells networks structure were investigated. The results show that the SSFs bending strength gradually increases and the open porosity falls with increasing the slurry loading in precursor; the bending strength remarkably improves and the open porosity reduces little by little......
Molecular dynamics simulation of bending crack initiation and growth of single crystal aluminiumSHAN De-bin(单德彬), YUAN Lin(袁 , 林), GUO Bin(郭 斌)(School of Materials Science and Engineering, Harbin Institute of Technology, Harbin 150001, China)Abstract:Molecular dynamics (MD) simulation was employed to research the mechanism of bending crack initiation and growth of single crystal aluminium......
the above NiFe2O4 spinel matrix material and copper-coated carbon fiber as raw materials. The effects of addition of copper-coated carbon fiber on the bulk density, porosity and bending strength were studied...% and the bending strength of samples is improved by about 22% with 3%(mass fraction) copper-coated carbon fiber. Key words: fiber/NiFe2O4 composite ceramic; inert anodes; copper-coated carbon fiber; two......
examined with an optical microscope (GX71, OLYMPUS, Japan). The flexural strength was studied using three-point bending test by computer servo control material testing machine (HT-2402-100KN, Taiwan, China...J. Cent. South Univ. Technol.
